Quick Detail

Description

The 3300 NSv Proximity Probe (Model 330901-00-09-70-02-05) is a high-performance eddy current transducer probe designed for precise measurement of vibration, shaft position, and rotational speed in compact industrial environments. Engineered for use with centrifugal air compressors, refrigeration compressors, process gas compressors, and other fluid-filmed bearing machines with tight installation constraints, this probe excels where traditional Bently Nevada 3300 and 3300 XL 5 mm and 8 mm transducers cannot fit. Featuring a linear range of 1.5 mm (60 mils) and a recommended gap setting of 1.0 mm (40 mils), it ensures accurate radial vibration and axial position detection on shafts smaller than 51 mm (2 in) or flat targets under 15 mm (0.6 in). The probe operates across an extensive temperature range of -52°C to +177°C (-62°F to +351°F) and is constructed from durable AISI 304 stainless steel with a chemically resistant PPS probe tip, ensuring reliable operation in harsh process environments. The included 7.0-meter (23 ft) standard cable with a Miniature coaxial ClickLoc connector enables secure, low-resistance connections while minimizing electromagnetic interference. Fully compatible with previous 3300 RAM systems, the NSv probe supports seamless upgrades, offering improved side-view characteristics, chemical resistance, and robust mechanical integrity via patented TipLoc and CableLoc designs, guaranteeing a pull strength of 220 N (50 lb). With a typical average scale factor of 7.87 V/mm (200 mV/mil), the 3300 NSv Proximity Probe delivers precise, repeatable measurement data for advanced automation, monitoring, and predictive maintenance applications.

Applications

1. Radial Vibration Measurement
Used to monitor radial vibration on shafts as small as 51 mm (2 in), ensuring accurate early detection of imbalance or bearing wear in high-speed compressors. Its 1.5 mm linear range allows precise measurements even in limited space installations.

2. Axial (Thrust) Position Detection
Ideal for axial monitoring on targets smaller than 15 mm (0.6 in), supporting shaft alignment verification and thrust bearing condition analysis to prevent excessive wear or catastrophic failures.

3. Tachometer / Zero Speed Monitoring
Provides real-time shaft speed detection with high accuracy, enabling automated control of centrifugal compressors and refrigeration systems, ensuring safety during start-up and shut-down sequences.

4. Phase Reference (Keyphasor) Signals
Generates reliable Keyphasor signals for vibration phase analysis, facilitating advanced machinery diagnostic systems and predictive maintenance in process gas compressor plants.

5. Compact Installation Applications
Designed for installations with counter bore, sideview, or rearview restrictions, such as small-footprint mechanical rooms, allowing precise sensor placement without compromising performance or accessibility.

Specifications

Competitive Advantage

1. Enhanced Side-View Capability
The 3300 NSv probe’s design supports side-view and reverse-mount installations, outperforming legacy 3300 RAM and 3000-series probes in tight mechanical spaces.

2. Superior Chemical Resistance
PPS probe tip and stainless steel case materials provide enhanced chemical resistance, enabling reliable operation in process compressors exposed to lubricants, refrigerants, or industrial fluids.

3. Seamless System Upgrade
Compatible with existing 3300 RAM extension cables and Proximitor Sensors, allowing easy upgrades without replacing the monitoring infrastructure, reducing downtime and installation costs.

4. Robust Mechanical Integrity
Patented TipLoc and CableLoc designs provide a 220 N pull strength, preventing probe tip detachment or cable failure in high-vibration industrial environments.

5. High Measurement Accuracy
With an average scale factor of 7.87 V/mm (200 mV/mil) and a 50 Ω output resistance, the probe ensures consistent and precise eddy current measurements, supporting predictive maintenance and automation control with minimal signal variation.
